This calculator subtracts two fractions. When fractions have different denominators, firstly convert all fractions to lớn common denominator. Find Least Common Denominator (LCD) or simple multiply all denominators to find common denominator. When all denominators are same, simply subtract the numerators and place the result over the common denominator. Then simplify the result khổng lồ the lowest terms or a mixed number.

Rules for expressions with fractions: Fractions - use a forward slash to lớn divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole và fraction parts.Mixed numerals (mixed numbers or fractions) keep one space between the integer andfraction & use a forward slash to input đầu vào fractions i.e., 12/3 . An example of a negative mixed fraction: -5 1/2.Because slash is both signs for fraction line và division, use a colon (:) as the operator of division fractions i.e., 50% : 1/3.Decimals (decimal numbers) enter with a decimal point . và they are automatically converted to fractions - i.e. 1.45.

The calculator follows well-known rules for the order of operations
. The most common mnemonics for remembering this order of operations are: PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction. GEMDAS - Grouping Symbols - brackets (), Exponents, Multiplication, Division, Addition, Subtraction.

MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule. Be careful; always bởi vì multiplication & division before addition và subtraction. Some operators (+ and -) và (* và /) has the same priority and then must evaluate from left to lớn right.
